Remove members of compact regression ensemble
cens1 = removeLearners(cens,idx)
Typically, set cens1 equal to cens to retain just one ensemble.
Removing learners reduces the memory used by the ensemble and speeds up its predictions.
Compact regression ensemble, constructed with compact.
Vector of positive integers with entries from 1 to cens.NTrained, where cens.NTrained is the number of members in cens. cens1 contains the members of cens except those with indices in idx.
Typically, you set idx = j:cens.NTrained for some positive integer j.
Compact regression ensemble, identical to cens except cens1 does not contain members of cens with indices in idx.
Create a compact regression ensemble. Compact it further by removing members of the ensemble.
Create a compact regression ensemble for the carsmall data.
load carsmall X = [Weight Cylinders]; ens = fitensemble(X,MPG,'LSBoost',100,'Tree','categorical',2); cens = compact(ens);
Remove the last 50 members of the ensemble.
idx = cens.NTrained-49:cens.NTrained; cens1 = removeLearners(cens,idx);
